Hi

I need a small size (approx 50mm by 100mm) low noise 16-channel ADC card
sending data on gigabit ethernet for real time data acquistion.
Minimum sampling (simultaneous) requirement per channel is approx 48
Ksamp/s/ch.

I know i ask for lot of things in very small size but if any one know some
commercially available adc cards near these specification, let me know it
please.

THANKS

You don't mention what interface you want, or if you want a single
board solution for both the e-net and the a2d.

but you might search for a SUMIT - sized board. If you can tolerate a
little larger size, there's this;

For your ADC have a look at http://www.enterpoint.co.uk/moelbryn/modules/adc_ad9727.html.
This module will do 200KHz / 16ch over the dual SPI interface. This
board can be hosted on a number of our FPGA development boards or
lashed up into another host with the Ethernet support.

On the hosting side our little USB board (Prog4)
http://www.enterpoint.co.uk/programming_solutions/prog4.html can be
used to host with a new 10/100 Ethernet module that we are about to
release if you want a compact solution. Our Drigmorn1
http://www.enterpoint.co.uk/component_replacements/drigmorn1.html is
another option but would need alternative headers fitted.

Gigabit Ethernet is more difficult but I don't understand why you
would need gigabit for this performance level of ADC.

Thanks for reply. I prefer a single board solution. PCM-MIO-G-AD-1
is a good option but size constraint is very strict for me.Second i need
individual channel sampling rate of 48Ksamp/s/ch and i donot think this
module full this requirement.

50 by 100 is a bit tight, but doable. Assuming you need 16 bit ADC
resolution this makes about 12 MbpS raw for all 16 ADCs.
Our netMCA is way larger and works at 10/100 MbpS, but given that
you order > say 10, I can fit it into 50x100 for you. I'll
need to know the ADC resolution, too.
It will cope with the 12 MSPS, you will be able to stream that
the over tcp.
